Upgrade your sleep with the Nautica Home Gellux® Cooling Gel Foam Mattress Topper. This plush mattress topper is made from advanced comfort foam to provide cushioning and ergonomic support. Patented Gellux® technology combines the benefits of cooling gel with a responsive foam. Because Nautica Home toppers are liquid gel-infused, they wick away body heat to help you sleep cool all night. A special Multi-Zone sculpted foam design promotes airflow and gives you lumbar support where you need it most. Finally, Air Flow perforations in the foam increase air circulation to prevent body heat build-up through the night. Firm mattress keeping you awake?
